mget - reads byte or word in a given binary format and convert to double

mgeti - reads byte or word in a given binary format return an int type

### Calling Sequence

  `x=mget([n,type,fd])`
  `x=mgeti([n,type,fd])`

### Parameters

- `n`:a positive scalar: The number of items to be read.
- `fd`: scalar. The `fd` parameter returned by the function `mopen`. -1 stands for last opened file. Default value is -1.
- `type`: a string. Give the binary format used to write all the entries of x.
- `x`: a vector of floating point or integer type numbers

### Description

The `mget` function reads data in the input specified by the stream parameter `fd` and returns a vector of floating point data. The `mgeti` function reads data in the input specified by the stream parameter `fd` and returns a vector of integer data.

Data is read at the position at which the file pointer is currently pointing and advances the indicator appropriately.

The `type` parameter is a conversion specifier which may be set to any of the following flag characters (with default value "l"):

  "l","i","s","ul","ui","us","d","f","c","uc": for reading respectively a long, an int, a short, an unsigned long, an unsigned int, an unsigned short, a double, a float, a char and an unsigned char. The bytes which are read are automatically swapped if necessary (by checking little-endian status). This default swapping mode can be suppressed by adding a flag in the `mopen` function. Format "l", "d" and "f" are valid only with the `mget` function.
  "..l" or "..b": It is also possible to read in little-endian or big-endian mode by adding a 'l' or 'b' character at the end of a type specification. For example "db" will read a double in big-endian mode.

### Examples

    file1 = 'test1.bin';
    file2 = 'test2.bin';
    fd1=mopen(file1,'wb');
    fd2=mopen(file2,'wb');
    mput(1996,'ull',fd1);
    mput(1996,'ull',fd2);
    mclose(fd1);
    mclose(fd2);

    fd1=mopen(file1,'rb');
    if 1996<>mget(1,'ull',fd1) ;write(%io(2),'Bug');end;
    fd2=mopen(file2,'rb');
    if 1996<>mget(1,'ull',fd2) ;write(%io(2),'Bug');end;
    mclose(fd1);
    mclose(fd2);
